John Davies, Head of the Competition Division, discusses regulatory reform and its impact on productivity and economic growth. The OECD has developed a toolkit to assess existing laws and regulations for their effect on competition. This toolkit was applied in a joint project between the OECD and Mexico's competition agency covering several sectors. It was also used to review four sectors in Greece, identifying over €5 billion in potential annual consumer benefits from regulatory changes. The document concludes with plans for the OECD to work jointly with Romania's competition council to review three sectors and provide recommendations.
